Step-by-step explanation:
Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.
Since EP⊥IJ, then segment JP is the height of the triangle EOJ.
The height of the equilateral triangle can be found using formula

where a is the side length.
So,

Therefore JP is 5√3 cm
It is how close it's form is to that of a circle, there is a formula for it that can be easily searched
